The most feature-complete open-source alternative to Google's NotebookLM — a self-hosted research platform where you upload PDFs, videos, audio files, and web pages into organized notebooks, then chat with your content, generate multi-speaker podcasts, and run semantic search across everything without sending a single byte to Google's servers. The podcast engine supports 1-4 fully customizable speakers with backstories, personalities, and expertise profiles, generating professional audio dialogue through OpenAI, ElevenLabs, Google TTS, or completely local text-to-speech via Kokoro for maximum privacy. Content processing uses token-based chunking with RAG-powered retrieval grounded in your uploaded sources, while both full-text keyword search and semantic vector search via SurrealDB enable conceptual discovery across all notebooks. The 18+ supported AI providers include OpenAI, Anthropic, Google Gemini, Groq, Ollama, LM Studio, and more — configurable per task so you can route cheap models to summarization and powerful models to analysis. Content transformations extract insights, generate summaries, create study guides, and produce structured outputs from any source material. The MCP integration connects Open Notebook to Claude Desktop, VS Code, and other MCP clients for seamless workflow integration. A full REST API on port 5055 enables complete automation of notebook management, source upload, and podcast generation. Deploy via Docker Compose with the application container, SurrealDB v2 on RocksDB, and optional TTS containers.

The utilities engineers otherwise scatter across a dozen ad-laden websites - 80+ of them - live together in IT-Tools, one fast, polished web app. Crypto covers JWT decoding, MD5 through SHA-512 hashing, HMAC and bcrypt generation, RSA key pairs, and password strength analysis. Converters handle JSON to CSV, YAML, and TOML, Base64 files, URL encoding, HTML entities, color formats, and Docker run commands to Compose files. Generators produce UUIDv4, ULID, BIP39 mnemonics, QR codes (including Wi-Fi QR), and tokens; text tools include a regex tester, diff viewer, slug and case converters; web utilities parse URLs and user agents, look up HTTP status codes and MIME types, and inspect Open Graph metadata; plus a cron parser, chmod calculator, and more. The privacy argument is the point: JWTs contain user IDs, hashes derive from passwords, JSON dumps hold PII - exactly the inputs you least want a third-party utility site to log. IT-Tools is a frontend-only static bundle (Vue/TypeScript, GPL-3.0, 39k+ GitHub stars) served by Nginx in one container, so everything runs client-side on your infrastructure with nothing transmitted anywhere. New tools ship roughly monthly, and a scaffolding script makes adding custom ones straightforward.

Private text, encrypted before it leaves the browser: Enclosed turns passwords, keys, and other secrets into a link that only its holder can open, with no third-party service in between. Can the server read the note? No. It stores only ciphertext and settings, because the decryption key rides in the part of the link after the # sign, which browsers never send. Want a second lock? Add a password, or generate a random one with a click, and share it by another route. Worried about links lingering in chat history? Pick one hour, one day, one week, or one month, and tick Delete after reading so the first view removes the note, with a warning shown to the recipient beforehand. Need more than text? Attach files by button or drag and drop, and recipients download them one by one or all at once. Sending to a phone? Every finished note offers a QR code, downloadable as SVG or PNG. Setting it up for a team? Restrict note creation to signed-in users, create notes from the command line, and let people read the interface in 17 languages with light, dark, or system themes.

End-to-end encrypted by design, CryptPad is a real-time office suite where teams write documents, plan on kanban boards, collect answers with forms, and draw diagrams without the hosting server ever seeing their content. Rich text pages come with comments, replies, @mentions, and a document outline, while the Markdown editor adds a live preview, Mermaid diagrams, mind maps, and math. Kanban columns hold colored, tagged cards with Markdown bodies, and the diagram editor exports PNG, JPG, SVG, or PDF. Optional ONLYOFFICE editors add spreadsheets, word-processing documents, and presentations that several people can edit together. The form builder offers text, choice, grid, date, ranking, and poll questions, conditional sections, and separate author, auditor, and participant roles. Documents can be shared with contacts or teams, by link, or as embed code, with view, edit, present, or view-once access. Passwords, expiry dates, owner lists, and access lists limit who gets in, and every edit lands in a history you can step through, restore, or pin as a named snapshot. CryptDrive keeps files in folders, tags, templates, and a trash bin, while teams get their own drive, chat, and member roles.

Google Analytics without the cookie banner or the maze of menus: Rybbit puts web and product analytics for every site you run on one readable dashboard, hosted on your own server. Pageviews, sessions, unique users, bounce rate, session duration, traffic sources, campaigns, devices, and countries update in real time beside a live visitor count. Session replay lets you watch the visits behind the numbers, and user profiles tie identified visitors to their sessions and events. Funnels pinpoint where conversions leak, journeys chart the paths people take through a site, retention reports show who comes back, and goals track conversions from page visits, custom events, and autocaptured clicks. Custom events carry JSON properties, filters slice every report across more than 15 dimensions, saved segments reapply them in one click, and location tracking drills from country to region to city on interactive maps, with optional 3D globe views through a Mapbox token. Error tracking connects JavaScript failures to the affected sessions, so a spike in errors leads straight to the visits that explain it. One install serves unlimited sites and organizations with role-based access, public dashboards share a site's stats through a link, and a tracking script of about 11 KB compressed collects data with no cookies and no consent banner. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

With over 5,100 GitHub stars and a proven track record powering more than 550,000 blogs on the Write.as hosted platform since 2018, WriteFreely strips blogging down to its essential purpose — writing — by removing news feeds, notifications, likes, and engagement metrics that distract from the creative process. The Go binary deploys on any platform as a single executable with SQLite for zero-dependency setups or MySQL and MariaDB for larger installations, consuming minimal system resources and running comfortably on hardware as small as a Raspberry Pi. The auto-saving Markdown editor provides a clean writing environment with instant draft preservation, while published posts render with typography-focused CSS that puts content front and center for readers. ActivityPub federation connects every blog to the fediverse, allowing Mastodon, Pleroma, and other ActivityPub platform users to follow blogs directly, receive new posts in their timelines, and boost or favorite content to their followers. Multi-blog support lets writers maintain separate blogs with distinct pen names from a single account without revealing their association, while OAuth 2.0 integration enables single sign-on onboarding from existing identity providers. Hashtag categorization organizes posts by topic, pinned posts create static pages for permanent content, and draft mode lets writers compose privately before publishing. Blog elements are localized in over 20 languages with first-class right-to-left script support for Arabic, Hebrew, and other RTL languages.

EdenText is a full word processor, from quick notes to full-length books, that opens the docx and odt files you already have and keeps them looking the way Word or LibreOffice made them. Pages are real pages: A4 or Letter sizes, margins, headers and footers, footnotes, columns, and watermarks, with mirrored margins and chapters opening on the right-hand page when you are laying out a book. Paragraph, character, table, and list styles cascade with inheritance and chapter numbering, and tables sort rows and compute spreadsheet-style formulas. The academic toolbox is complete: table of contents, captions, cross-references, citations with bibliography, an alphabetical index, and LaTeX formulas. Reviewing works the way editors expect, with tracked changes, threaded comments in margin balloons, printable markup, spell checking in eight languages, and grammar checking for English. An optional AI assistant answers questions about the document and proposes edits as tracked changes through your own model provider. Nothing waits on a server: documents autosave in the browser, the app installs and works offline, and your words never leave the machine. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

With over 38,000 GitHub stars, nearly one million registered users, and over 1.3 million resumes created, Reactive Resume delivers a professional resume creation experience that rivals commercial platforms like Resume.io and Zety without collecting user data, showing advertisements, or imposing paywall restrictions. The real-time WYSIWYG editor renders changes instantly as users type, providing immediate visual feedback across all resume sections including work experience, education, skills, certifications, projects, and custom sections with typed extensions. Over fifteen professionally designed templates with full color customization, font selection, spacing adjustment, and icon style selectors ensure each resume reflects individual style preferences. The drag-and-drop system lets users move items between sections and pages freely across multi-column and full-width layouts. PDF generation produces pixel-perfect documents using a headless Chromium rendering pipeline, ensuring consistent output across all devices and print settings. Multi-language support covers over twenty languages with RTL script handling for Arabic and Hebrew. Authentication supports passkeys and multiple OAuth providers via Better Auth, while self-hosted deployment runs via Docker Compose with PostgreSQL and Browserless for PDF rendering. The import system accepts JSON Resume format, LinkedIn data exports, and PDF/DOCX files when AI integration is configured. AI-powered content suggestions using OpenAI, Google Gemini, Anthropic Claude, or local Ollama models help improve bullet points and professional summaries. A CSS editor with autocompletion allows fine-grained styling control. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Open the page, write a Markdown note, move on - Memos is a lightweight, self-hosted service built for quick capture. Instead of folders, notebooks, and titles, it presents a timeline: open the page, write a Markdown note, and move on. Notes support headings, code blocks with syntax highlighting, task lists, tables, and file attachments, with tags auto-extracted from #hashtags in the text. Each memo carries a visibility level, private, protected (logged-in users), or public, so one instance works as a personal log, a small team wiki, or a lightweight microblog. The backend is a single Go binary with a React frontend, around 50 MB of memory at runtime and a ~20 MB Docker image, so it fits comfortably on the smallest instance size with near-zero maintenance. SQLite is the default store, with MySQL and PostgreSQL supported for multi-user deployments needing more concurrency, and full REST and gRPC APIs - Connect RPC for browsers, gRPC-Gateway for external tools - make capture scriptable from CLIs, bots, and automation platforms. Fast full-text search spans all memos, pinned notes keep references handy, and a masonry view suits visual browsing. MIT-licensed with zero telemetry; content is stored as plain Markdown in a database you control, so notes remain readable, exportable, and free of proprietary formats.

Known as the open-source Mixpanel alternative that respects user privacy, OpenPanel delivers a unified web and product analytics platform combining Mixpanel's behavioral analysis with the simplicity of Plausible and full data ownership through self-hosting. Cookieless tracking eliminates consent banners entirely while still capturing events, page views, sessions, user journeys, funnels, retention cohorts, and custom properties with full GDPR compliance by design. The 2.3 KB async script loads without blocking page rendering, and 16 official SDKs cover Next.js, React, Vue, Astro, Remix, Nuxt, Angular, Svelte, React Native, Swift, Kotlin, Python, PHP, Laravel, Express, and REST API for custom integrations. Real-time dashboards display live visitor counts, active sessions, and event streams as they happen. Custom chart builders create tailored visualizations from any tracked event with breakdowns by property, time period, and user segment. Session replay reconstructs individual user journeys showing every page visited, event triggered, and interaction recorded. Funnel analysis identifies conversion drop-offs with step-by-step breakdown and property filtering. Retention analysis measures how often users return with customizable time windows and cohort comparisons. A/B testing and variant tracking enable experiment measurement directly within the platform. Event notifications alert when specific events occur or thresholds are crossed. The self-hosted deployment uses Docker Compose with ClickHouse for high-speed analytical queries, PostgreSQL for metadata, and Redis for real-time processing — deployable on any VPS or Kubernetes cluster. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Two decades of continuous development made Roundcube the standard-bearer of open-source webmail - a PHP IMAP client that gives any mail server a polished, application-like interface in the browser. It connects to whatever IMAP/SMTP stack you run - Dovecot, Postfix, a hosted mailbox - and delivers the full desktop-client experience: drag-and-drop message management, threaded conversation views, full MIME and HTML mail handling, find-as-you-type address book with groups and LDAP connectors, multiple sender identities, full-text search, and spell checking in dozens of languages. The default Elastic skin is genuinely responsive, working as well on a phone as a desktop, and the entire UI is skinnable. The plugin API is where deployments get shaped: managesieve exposes server-side filter management in the UI, enigma brings PGP encryption and signing via GnuPG, markasjunk trains spam filters, zipdownload batches attachments, password lets users change credentials, and attachment_reminder catches the classic forgotten-attachment email - among hundreds of community plugins. Built-in caching keeps large mailboxes fast, IMAP ACLs and shared folders support team setups, and XSS protection is engineered into the rendering pipeline. It scales from a single personal mailbox to unlimited users, backed by MySQL, MariaDB, PostgreSQL, or SQLite. GPL-licensed with regular security releases.

With nearly 3,000 GitHub stars and active development since 2014 through version 14.2.0, Yopass eliminates the universal bad habit of sharing passwords and API keys through Slack messages, email threads, and ticket systems by encrypting secrets entirely in the browser using OpenPGP before anything reaches the server. The Go backend stores only ciphertext — it never sees plaintext — while the React frontend handles all encryption and decryption client-side, generating one-time URLs that self-destruct after a single viewing or when the configured expiration of one hour, one day, or one week passes. File upload support streams encrypted files with configurable size limits, and optional custom password protection adds a second encryption layer beyond the URL-embedded key. The server supports Redis or Memcached as storage backends with automatic key expiration, deploying via Docker Compose in under five minutes or as Kubernetes manifests for production environments. Built-in TLS support works alongside reverse proxy configurations for Nginx, Caddy, and Traefik with automatic Let's Encrypt certificate provisioning. Prometheus metrics expose HTTP request counts, latency histograms, and secret lifecycle counters for Grafana dashboard integration and alerting. Read-only mode enables split-instance deployments separating secret creation from retrieval across different network zones. Multi-language support localizes the interface for international teams. The open-source core under Apache 2.0 provides full self-hosted functionality with no account management required. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

No cookies, no fingerprinting, no cross-site tracking, no personal data collection - Umami's privacy contract is the foundation of the open-source web analytics platform. IP addresses are hashed rather than stored, which makes it GDPR, CCPA, and PECR compliant by default - the consent banner can come off the site entirely. The tracking script is under 2 KB, roughly 20x smaller than Google Analytics, so measurement stops being a page-weight tax. The dashboard covers the core metrics - pageviews, visitors, bounce rate, visit duration, referrers, browsers, devices, and countries - with any date range and filtering by country or device. Beyond pageviews, custom events track clicks, form submissions, and signups via a data attribute or one JavaScript call, and advanced reports add funnels, user journeys, retention and cohort analysis, goals, and automatic UTM campaign tracking. Anonymous session views show individual visitor activity without identifying anyone. Teams share websites with role-based access, one instance manages unlimited sites, and a full REST API exposes every metric programmatically. MIT-licensed and self-hosted on PostgreSQL or MySQL via Docker, your analytics data never leaves your infrastructure.

One statically-compiled Go binary over PostgreSQL, no ORM, no framework, static assets embedded in the executable: Miniflux is the minimalist, opinionated feed reader. The opinions are the feature: page layout, fonts, and colors are tuned for reading, and everything else is treated as noise. It consumes Atom, RSS, and JSON Feed formats with OPML import/export, organizes articles with categories and bookmarks, fetches original full-text content for summary-only feeds, and provides Postgres-powered full-text search. Privacy work happens automatically: pixel trackers are stripped, tracking parameters removed from URLs, a media proxy blocks third-party tracking, referrers are never forwarded, and there is zero telemetry. Navigation is keyboard-first - j/k through items, o to open, f to star - with touch gestures on mobile. Podcast, video, and music enclosures are supported, and YouTube videos play inline. Over 25 integrations save articles onward to Wallabag, Readwise Reader, Pinboard, Linkding, Instapaper, Notion, Telegram, Matrix, Ntfy, and more, plus webhooks and a REST API with Go and Python clients; the Google Reader API endpoint supports existing mobile reader apps. Authentication spans local passwords, passkeys (WebAuthn), Google OAuth2, OpenID Connect, and reverse-proxy headers. It is Apache 2.0 licensed, translated into 20 languages, and updates feeds on an internal scheduler.

Running a VPN for family, friends, or a small team usually means babysitting servers one SSH session at a time, and Mistgate replaces that with one panel that keeps the whole fleet configured. Add a server from the browser by typing its address and root password: the panel pins the host key, checks the host, opens the ports, and installs the signed node agent for you. Each person gets one subscription link that their app turns into the server list, or a personal AmneziaVPN key per device, so a lost phone can be revoked without touching anyone else. Groups decide which protocol profiles a person receives, while per-user traffic quotas, expiry dates, device limits, and per-device speed limits keep sharing fair. Hysteria2 brings QUIC-based speed with port hopping, obfuscation, and certificate options; VLESS REALITY and AmneziaWG 2.0 and 3.1 cover networks where one protocol gets blocked, and Cloudflare WARP can serve as the exit for all three. Every five minutes the panel connects to each server the way a real client app would, a doctor on every node runs host checks with safe fixes, and alerts reach you on Telegram before your users notice. The public address shows strangers a decoy site while the admin hides behind a secret path, and encrypted backups go to your Cloudflare R2 bucket on a schedule. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Page views, funnels, session replays, error reports, Core Web Vitals, and uptime checks share one cookieless dashboard in Betterlytics, so teams stop stitching several tools together. The overview charts visitors, page views, bounce rate, and visit duration against the previous period, and annotations mark launches or campaigns right on the timeline. Breakdowns cover referrers, channels, UTM campaigns, browsers, devices, and operating systems, with visitor locations on a world map once an optional MaxMind key is added. Custom events, global properties such as plan or app version, and outbound link tracking show what visitors actually do, while user journey diagrams and funnels reveal where they drift away. Session replay is opt-in per tracking script, masks text and form inputs by default, and can keep recordings in your own S3-compatible bucket. Error tracking groups JavaScript errors with stack traces, a session trail, and a link to the matching replay. Uptime and SSL monitors alert through Slack, Discord, Teams, or webhooks and feed public status pages on your own domain. Teammates join by invitation, two-factor login is available, and a built-in MCP server lets Claude, Cursor, or Codex answer traffic questions. A script of about 3.5 KB or a WordPress plugin handles installation. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

The ad-riddled "free online tools" sites people paste sensitive text into and upload confidential PDFs to - OmniTools replaces that whole ecosystem with one self-hosted app. It bundles 50+ utilities behind one clean React/TypeScript interface: image tools (resize, convert, crop, edit), video and audio tools (trim, reverse, convert), PDF tools (split, merge, edit), text and list utilities (case converters, formatters, shufflers), plus date/time, math, and data-format helpers for JSON, CSV, and XML. The architectural decision that makes it trustworthy is that all file processing happens entirely client-side in the browser - the server only serves static assets, and nothing you process ever leaves your device. That design has a pleasant side effect: the host needs almost no resources (people run it on a Raspberry Pi Zero), because your browser does the work while the server just delivers files. The Docker image is a remarkable 28 MB, making it one of the fastest apps to deploy and cheapest to keep running. There are no ads, no tracking, no accounts, and no upload limits. With multi-language support and an MIT license, it works equally well as a personal toolbox or a team-wide internal utility portal - one URL that replaces a bookmark folder full of questionable converters. Actively developed with 50 contributors and 9,500+ GitHub stars.

Websurfx aggregates results from multiple search engines into one private, ad-free interface that never tracks your queries. Written in Rust, the backend provides memory safety against buffer overflows and data races at the language level while handling concurrent requests across upstream providers like DuckDuckGo and Searx. A built-in re-ranking algorithm scores and merges results by relevance, producing a unified page that draws from many sources while appearing as one coherent search. Safe-search filtering operates across four levels from unrestricted to complete content blocking, with regex-based filter lists for parental controls in schools and organizations. Upstream requests route through configurable proxy chains or Tor, preventing search providers from correlating your queries with a specific IP address. Four Docker image variants target different caching strategies: hybrid Redis plus in-memory for maximum throughput, Redis-only, in-memory-only, or zero-persistence for environments where cached queries must never touch disk. The Lua configuration file controls engine selection, request timeouts, rate limiting thresholds, and production-mode delays that throttle upstream traffic to prevent abuse. Quick-result widgets handle calculations, currency conversions, and unit transformations inline without external redirects. Image search capabilities serve visual discovery for designers and researchers who need media results without surveillance. Runs on a RepoCloud VPS with dedicated resources and full root access. AGPL-3.0 licensed.
